RTA furniture shipped in flat-pack form is generally classified based on its finished-product identity under HTS rules for incomplete or unassembled articles, meaning it typically falls under the same heading as the assembled version. However, country-of-origin rules for RTA goods can be complex when components are sourced from multiple countries, and substantial transformation analysis may be required to determine the correct origin for duty purposes.

Institutional furniture for healthcare settings may need to meet BIFMA performance standards, California TB 117 or TB 133 flammability requirements, or facility-specific procurement specifications. While these are not customs-entry requirements per se, failure to meet them can result in rejection by the buyer and costly returns, making pre-shipment specification verification essential.
